Summary:
Improving experience when editing group-by column:
- Disable column rename
- Allow changing most widget properties:
- Color/Background
- Number format
- Date/DateTime format (but not the timezone)
- All toggle options (for toggle column)
- Remove Edit button on Choice Edit
- Changing the underlying column should reset all those options back to the original column.
